IEC 60601-2-28:2017+AMD1:2026 CSV – Medical electrical equipment

IEC 60601-2-28:2017+AMD1:2026 CSV defines particular requirements for the basic safety and essential performance of X-ray tube assemblies used in medical diagnosis and imaging. As a consolidated version of the third edition, it incorporates Amendment 1 and aligns with the amended third edition of the general standard IEC 60601-1. The page below presents an interpretive overview of the standard, its scope, and its place within the IEC 60601 framework.

Standard Information

X-ray tube assemblies are core components of diagnostic imaging systems, and their safe operation depends on requirements that address their particular construction and function. This particular standard interprets the general and collateral requirements of the IEC 60601 framework as they apply to X-ray tube assemblies. It exists as a consolidated version, merging the third edition with its amendment so that users can work from a single document. The record facts are as follows: - Designation: IEC 60601-2-28:2017+AMD1:2026 CSV
- Full title: Medical electrical equipment - Part 2-28: Particular requirements for the basic safety and essential performance of X-ray tube assemblies for medical diagnosis
- Status: Current
- Publication date: 2026-09-16
- ICS classification: 11, 11.040, 11.040.55
- Technical committee: TC 62/SC 62B

Scope and Application

The standard applies to the basic safety and essential performance of X-ray tube assemblies and to components thereof, intended for medical diagnosis and imaging. Within this particular standard, references to ME equipment in the general standard IEC 60601-1 and the collateral standard IEC 60601-1-3 are interpreted as references to X-ray tube assemblies. This substitution allows the general framework to be applied to the assembly level rather than to a complete device. A structural rule governs how clauses are read. Where a clause or subclause is specifically intended to apply to ME equipment only, or to ME systems only, the title and content of that clause state this explicitly. Where no such statement appears, the clause applies both to ME equipment and to ME systems, as relevant. Users of the document must therefore check clause titles before deciding applicability. The third edition was prepared to fit IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012, the amended third edition of the general standard, which the document refers to as the general standard. Beyond the changes related to that amendment, the document also includes changes related to technical improvements.

Products and Materials Covered

The products in scope are X-ray tube assemblies intended for medical diagnosis and imaging, together with components of such assemblies. An X-ray tube assembly, in the context of this document, is treated as the item of ME equipment to which the particular requirements apply. This means the requirements are directed at manufacturers of the assembly and its components, not solely at manufacturers of complete imaging systems. The ICS classification confirms the domain. Class 11 covers health technology, 11.040 covers medical equipment in general, and 11.040.55 covers diagnostic instruments as a specific family. Together these classes situate the standard within medical diagnostic equipment, consistent with the stated scope of diagnostic X-ray imaging components. No other product families fall within the documented scope.

Testing and Compliance Considerations

For a particular standard of this type, testing laboratories typically work within the structure established by the general standard: the particular requirements either replace, add to, or modify corresponding clauses of the general standard. A type test programme is therefore assembled by reading the two documents together, clause by clause, and recording which requirement takes precedence for each aspect of basic safety and essential performance. Documentation underpins the process. Manufacturers are normally expected to supply a risk management file, technical construction documentation, and declarations of which clauses of the general standard remain applicable. Test engineers verify conformity against the applicable clauses, and any deviations or modifications introduced by the particular standard must be reflected in the test plan befOre testing begins. Retest triggers deserve attention. Design changes to the tube assembly, changes in supplied components, or amendments to the referenced general standard can each prompt a reassessment of whether earlier results remain valid. Because this document is a consolidated version, laboratories confirm which amendment status applies to a submitted sample so that the correct requirement set is used throughout evaluation.

Related Standards and Series Context

The designation itself carries structural information. IEC 60601 is the series number for medical electrical equipment standards; Part 2-28 identifies this document as a particular standard, one of the Part 2 group that addresses specific equipment types, with 28 assigned to X-ray tube assemblies. The year 2017 marks the edition publication, while "+AMD1:2026 CSV" indicates a consolidated version that merges the 2026 Amendment 1 into the base text, giving a publication date of 2026-09-16 for the consolidated document. The CSV format has practical value: readers consult one continuous text rather than a base edition plus a separate amendment. Responsibility for the document lies with technical committee TC 62/SC 62B, the subcommittee that maintains standards in this equipment area. Readers who need the authoritative text should obtain it through official IEC distribution channels; this page is an interpretive overview only.
